Not me. I guess I was a purist so I wasn't thinking outside the Lego box to develop a sufficient friction solution to the weight problems. I came up with some messed up designs, but they were only marginally more effective than traditional black Technic friction pins, and they use many more pieces. You can see in Turn 6 of the QoP Part 3 battle the front two legs of the Assyrian S-143 have modified joints connecting them to the body of the tank. The paper solution is super effective compared to the other things I tried.
